Discover magazine published an article detailing the discovery by wildlife biologist Dr. Aprile Pazzo of a fascinating new species: the hotheaded naked ice borer. Dr. Pazzo, the article explained, encountered this creature while studying penguins in Antarctica. She noticed a frightened penguin rapidly sinking into the ice, and when she pulled the hapless creature out of the rapidly growing slush pool, she found small, bizarre animals attached to its lower body. They were about half a foot long, and quite light. Their unique feature was a bony plate on their head that they could cause to become burning hot, allowing them to bore tunnels through the ice at high speeds, "much faster than a penguin can waddle." Packs of them would rapidly melt the ice beneath a penguin, causing it to sink into the slush, at which point they would surround the creature and consume it. Dr. Pazzo hypothesized that the hotheads might have been responsible for the mysterious disappearance of noted Antarctic explorer Philippe Poisson in 1837. "To the ice borers, he would have looked like a penguin," she was quoted as saying. Discover received an enormous amount of mail in response to this article. The responses of most readers were very tongue-in-cheek, but a few readers were annoyed that Discover had taken liberties with the trust of its readers.
